hello list

a very simple question i hope

how do we access the guile posix/sockets functions from within an r6rs
library?

in ikarus there is (import (ikarus)), is it something similar?

i see they are automatically present in the interpreter

best,
rohan

$ guile --r6rs
GNU Guile 3.0.4
[...]
scheme@(guile-user)> socket
$1 = #<procedure socket (_ _ _)>
scheme@(guile-user)>
$ cat test.scm
#!r6rs
(library (test)
  (export udp-open)
  (import (rnrs))
  (define udp-open
    (lambda (h p)
      (let ((s (socket PF_INET SOCK_DGRAM 0)))
        (connect s AF_INET (inet-pton AF_INET h) p)
        (list s h p)))))
